s explained in Chapter 1, the Tools panel is home to many of Photoshop’s
most important implements. This appendix gives you a quick rundown of
everything in this virtual toolbox and points you to where you can learn
more about each tool.
Note: In this appendix, each tool’s keyboard shortcut is listed in parentheses after its name. As you
learned on page 23 in Chapter 1, all the tools in a given toolset share the same keyboard shortcut.
Move, Selection, and Crop Tools
These are the tools you use to tell Photoshop what part of an image you want to edit
or trim. Once you’ve created a selection, you can move those pixels to another spot,
change their color, apply a filter to them, and so on. The selection tools are covered
in detail in Chapter 4.
• The Move tool (V) is the black arrow at the top of the Tools panel (see Figure
D-1, left). You can use it to grab and move a selection (page 177), whole layers
(page 96), and guides (page 70).
• The Marquee tools (M) are nestled just below the Move tool; they include the
Rectangular, Elliptical, Single Row, and Single Column Marquees. You’ll use the
Rectangular Marquee the most as it’s great for selecting square and rectangular
areas. To use any of these tools, just click and drag diagonally and Photoshop
marks your selection with an army of marching ants (page 136).

Move, Selection, and
Crop Tools
Figure D-1: Left: The Move tool perches at the very top
of the Tools panel, followed by the Marquee
toolset. You can find a toolset’s keyboard
shortcut by opening the toolset’s menu or
hovering your cursor over the tool for a few
seconds until a yellow tooltip appears.
Right: Photoshop’s Lasso toolset includes the
Lasso, Polygonal Lasso, and Magnetic Lasso
tools.
Tip: To cycle through the different tools in a toolset, add the Shift key to that group’s keyboard shortcut.
For example, to switch between the Rectangular and Elliptical Marquee tools, press Shift-M.
• The Lasso tools (L) let you draw selections by hand (page 162). They’re great
for selecting irregular-shaped areas or objects that you can’t get with the Marquee tools. To use the basic Lasso tool, click where you want the selection to
start and then drag to draw an outline around the rest of the object. When you
release your mouse button, Photoshop automatically adds a straight line that
connects the start and end points of the line you drew. The Polygonal Lasso tool
is handy for selecting objects with a lot of angles because it draws only straight
lines; you simply click when you want to change directions. The Magnetic Lasso
tries to guess what you want to select as you hover your cursor over an object.
• The Quick Selection tool (W) lives just below the Lasso tools (see Figure D-2,
left). Click or click and drag with this tool across the area you want to select,
and Photoshop tries to figure out the shape of the object you’re after by selecting areas that are similar in color to the ones you “brush” across (page 149). It’s
great for grabbing selections based on color, and the painting metaphor makes
it simple to use.
Figure D-2: Left: The Quick Selection and Magic Wand tools make
selections based on color.
Right: Use the Crop tool to remove unwanted bits around
the edges of your images and the Slice tool to chop up
images destined for life on the Web.
• The Magic Wand tool (W) also creates selections based on color (its icon looks
like a wizard’s wand). Click once on the color you want to select and Photoshop
grabs all the contiguous pixels that are similarly colored (page 151). You can

Move, Selection, and
Crop Tools
then Shift-click to add an area to the selection or Option-click (Alt-click on a
PC) to subtract an area from the selection.
• The Crop tool (C) lets you trim distracting elements from the edges of your image, as well as change the size of your image. Simply use it to draw a box around
the part of the image you want to keep and then press Return (Enter on a PC) to
delete everything outside the box. Page 222 has the details.
• The Slice tools (C) let you carve your images into pieces that’ll end up on a web
page (page 731). The Slice tool looks and acts like an X-Acto knife—it records
how you’d like your image chopped up once it’s saved for the Web (it doesn’t
make any changes to the way your image looks). The Slice Select tool lets you
choose slices and move them around or assign URLs to them. Chapter 17 has
the scoop on slicing and dicing your images for life on the Web.
• The Eyedropper tool (I) lets you choose a color you want to use as your foreground color chip (page 14). It looks—not surprisingly—like an eyedropper
(see Figure D-3, top), and it’s extremely useful for picking colors for painting
(Chapter 12), creating new backgrounds (page 47), and color-correcting images (Chapter 9). In Photoshop CS5, this tool includes a Sample Ring option—a
.25"-wide circular band around the cursor that displays the previously chosen
color on the bottom half and the new color on the top; it makes snatching just
the right color a snap.
• The Color Sampler tool (I) marks the spot you click with a number and logs
the color value of those pixels in the Info panel. Use this tool to color-correct by
the numbers as explained on page 401.
• The Ruler tool (I) measures the distance and angle between two points in your
image and displays that info in the Options bar and Info panel (its button looks
like a little ruler). All you need to do is drag from one point to another and
then release your mouse button—Photoshop calculates the distance between
the points and the angle of the line. In CS5 you can use this tool to straighten
crooked images. See page 71 for the lowdown.
• The Note tool (I) looks like a small Post-It note, and lets you add annotations
to your documents. To add a note, simply select this tool, click where you want
the note to appear, and Photoshop opens the Notes panel so you can type your
comments (see Figure D-3, bottom).
• The Count tool (I) is available only in Photoshop CS5 Extended (page 1). This
tool was added to help researchers count objects (such as blood cells) in digital images. If you use this tool in manual mode, Photoshop tracks how many
times you click in an image and displays a running total in the Measurement
Log panel (Window➝Measurements Log). To make Photoshop count items for
you, use the Magic Wand tool to select the objects you want to count. Then
choose Analysis➝Select Data Points➝Custom, make sure the Count option is
turned on, and then click OK. Finally, choose Analysis➝Record Measurements
to open the Measurements Log panel and display your tallied results.

Retouching and
Painting Tools
Figure D-3: Top: Pick a color, any
color—that’s what the
Eyedropper and Color
Sampler tools are
for. The Ruler, Note,
and Count tools don’t
have anything to do
with color but they
live in this toolset just
the same.
Bottom: Notes are
great for adding
reminders to specific
parts of an image,
passing love notes,
and so on. To read a
note, double-click its
icon and Photoshop
opens the Notes
panel. To delete a
note, select it with the
Move tool and then
click the tiny trash can
at the bottom of the
Notes panel (circled).
Retouching and Painting Tools
You can use the retouching tools to repair and enhance your images (for the scoop
on retouching people, flip back to Chapter 10). In the Tools panel, the retouching
tools are grouped with the painting tools because most of them are brush-based
(meaning they use a brush cursor). The Brush tool is covered extensively in Chapter
12 (where you’ll also find some bonus info on color theory).
Since these tools are brush-based, you aren’t limited to the standard round brush
cursor with different hardness or opacity levels. You can select any of the custom,

Painting Tools
preset, or sampled brushes covered in Chapter 12, which gives you a wide range of
options to experiment with when applying effects or retouching your images. To
change the brushstroke, just hop up to the Brush menu in the Options bar.
• The Spot Healing Brush (J) looks like a Band-Aid with a circle underneath
it (see Figure D-4, left), which is appropriate because it’s designed to remove
round blemishes. If you make your cursor slightly larger than the blemish you
want to zap and then click the offending blemish, Photoshop blends the area
you clicked with the surrounding pixels. In Photoshop CS5, this tool scored a
new option called Content-Aware Fill which helps retouched areas blend more
accurately with surrounding pixels. You can see it in action on page 425.
Figure D-4: Left: You can use the healing tools to do digital
plastic surgery.
Right: Because so many tools are brush-based,
you’ll end up using the brush cursors more than
any other kind.
• The Healing Brush (J) lets you repair imperfections that aren’t round. This
tool also looks like a Band-Aid and you can use it to fix wrinkles, dark circles,
and so on. You tell Photoshop what you want the problem area to look like by
Option-clicking (Alt-clicking on a PC) a good area and then simply paint the
imperfection away as explained on page 427.
• The Patch tool (J) works like the Healing Brush except you draw a selection
around the problem area in your image and then drag your selection to a good
area—Photoshop blends the two areas together with remarkably good results.
This tool is great for fixing bags beneath eyes or getting rid of small objects you
don’t want in your image (see page 431).
• The Red Eye tool (J) does just what its name implies: You use it to draw a box
around the offending eye (the whole eye, not just the pupil), and Photoshop
identifies the problem red area and replaces it with dark-gray pixels. See page
452 for the scoop.
• The Brush tool (B) lets you paint with a variety of brushes; its icon looks like—
you guessed it—a little brush. Photoshop includes a ton of built-in brushes, but
you can also edit them and create your own. This tool is covered in great detail
in Chapter 12. Photoshop CS5 includes a slew of new brush tips that behave like
their real-world counterparts—their bristles even splay when you paint!
• The Pencil tool (B) is really a hard-edged brush that gives you few options
other than changing its size. It’s not terribly useful because, if you draw with
it, you’ll produce extremely jagged lines. This tool does have one cool feature,
appendix d: photoshop’s tools panel

Retouching and
Painting Tools
though: Auto Erase, which lets you undo brushstrokes by painting back over
them (see page 508). If nothing else, it’s a cool trick to show friends. Otherwise,
stick with the Brush tool for your painting needs.
• The Color Replacement tool (B) lets you substitute one color for another by
painting over the area. It’s great for removing super-stubborn red eye. Page 454
has the details.
• The Mixer Brush (B) is new in Photoshop CS5. You can mix paint with it (either new paint or color from an existing photo), set it to clean itself after each
stroke, and more. It’s just the ticket for creating realistic painting effects, as
shown on page 502.
• The Clone Stamp tool (S), whose icon looks like an old-fashioned rubber stamp
(see Figure D-5, left), works a little differently than the healing and patch tools.
Instead of blending pixels together, it copies part of an image to another spot.
Page 312 shows you how to use it to clone an object from one image to another,
and page 434 explains how it can help you zap shines and shadows in portraits.
Figure D-5: Left: Photoshop’s Clone Stamp tool can copy part of
your image to another spot in the same image, or to
another image entirely. Use the Pattern Stamp tool to
paint with Photoshop’s built-in patterns or one that
you’ve created.
Right: Some brushes add to your images, others take
away. The History and Art History brushes wipe away
your edits to reveal how your image looked before you
changed it.
• The Pattern Stamp tool (S) lets you paint patterns on your image, and its icon
looks like a rubber stamp. Even though it’s called a stamp, it acts more like a
brush. Pick a pattern in the Options bar and then paint away. If you don’t like
the pattern presets that come with Photoshop, you can load the other pattern
libraries or create ones of your own. The steps for making your own pattern
are the same as for creating your own brush (page 531) except that you choose
Edit➝Define Pattern instead.
• The History Brush (Y) is like a time machine because it lets you paint over
parts of your image to reveal a previous version of your work. See page 29 to
learn more.
• The Art History Brush (Y) lets you add bizarre effects to your image by painting to expose a previous state, but with an extra twist: Instead of simply revealing what was there before, it applies effects so the image looks rather impressionistic. It’s covered in the box on page 536.

Retouching and
Painting Tools
• The Eraser tool (E) lets you paint to erase parts of your image. Its icon looks
like the pink erasers you used in elementary school (see Figure D-6, left), and
it works nearly the same way: Grab it from the Tools panel and select a mode
from the Options bar (Brush, Pencil, or Block mode), and then drag across your
image to erase pixels in that area. Erasing on a layer removes pixels from just
that layer, while erasing on the Background layer replaces those pixels with your
background color (see the box on page 85 for more on the Background layer).
Figure D-6: Left: You can easily zap unwanted pixels with the
Eraser tool.
Right: The Gradient and Paint Bucket tools let
you fill a selection or entire layer with color.
• The Magic and Background Eraser tools (E) do their best to remove backgrounds from your images while leaving the foregrounds intact. They work by
examining the colors of the pixels you brush across (or click) and erasing nearby
pixels with similar color values. You can see them both in action on page 157.
Tip: The Magic and Background Eraser tools are great for removing small areas in your image, but if you
need to hack away big chunks, use the Quick Selection tool instead.
• The Gradient tool (G) lets you fade one color into another to create backgrounds or add color overlays to your images. It looks like a rectangle filled
with black that fades to white. You can use it to fill areas you’ve selected, text
(page 621), or whole layers. When used with a layer mask, it’s great for gradually
fading one image into another (page 287), applying a colored tint (page 363) or
fading a colored image to black and white (page 334).
• The Paint Bucket tool (G) fills areas with solid color. It’s the tool equivalent
of the Edit➝Fill command (page 181). It uses whatever color your foreground
color chip is set to (page 24), so be sure to change that color before reaching for
this tool.
• The Blur tool lets you paint to make parts of your image look like they’re out
of focus. Its icon looks like a raindrop (see Figure D-7, left), perhaps because
real water drops blur paint. Since it uses a brush cursor, you can use the Options
bar to set its size and hardness. (A harder brush leaves more defined edges in its
wake; a softer brush leaves more of a blur.)

Retouching and
Painting Tools
Figure D-7: Left: You can use the Blur and Sharpen tools to edit only the
areas that need fixing. Be sure to adjust their Strength settings
in the Options bar, as they’re extremely destructive.
Right: The Dodge and Burn tools let you lighten and darken
your image (respectively) by hand using a brush cursor. Even
though they were revamped back in Photoshop CS4, they’re
still fairly destructive and, if you’re not careful, can inflict serious harm on your image. To learn how to use the Brush tool
to create the same effects, flip back to page 447.
• The Sharpen tool, whose icon looks like a tall triangle, enhances the contrast
around an object’s edges to make it look clearer. It’s helpful when you need to
sharpen really small areas by hand. By lowering its Strength in the Options bar,
you can keep from totally destroying your image (see the box on page 474). That
said, Chapter 11 is chock-full of safer sharpening techniques.
• The Smudge tool works like a digital finger you can drag across an image to
smear it as if you were finger painting. You can adjust its cursor size and mode
in the Options bar. Its factory setting samples (copies) colors from the current
layer only; if you want it to sample from all layers, turn on the Sample All Layers
checkbox. Turning on the Finger Painting checkbox makes this tool paint with
the current foreground color instead of the colors in your image.
Note: The Blur, Sharpen, and Smudge tools don’t have keyboard shortcuts. Maybe because you’ll rarely
use ’em!
• The Dodge tool (O) lets you lighten parts of your image using a brush cursor,
much like old-school photographers used the dodging technique to control exposure in their darkrooms (see page 448). The key to success with this tool is to
lower its Exposure setting in the Options bar significantly.
• The Burn tool (O) works just like the Dodge tool except it darkens parts of your
image. (Its icon looks like a hand making an “O” shape.) Here again, be sure to
significantly lower the Options bar’s Exposure setting because its factory setting
is way too strong (see page 448).
• The Sponge tool (O) works with the Dodge and Burn tools, but it doesn’t
change an image’s exposure. Instead, it increases or decreases its color saturation, as explained on page 455. It can be handy when you need to drain a very
small area of color (such as a stubborn red eye).

Drawing and Type
Tools
Drawing and Type Tools
These tools let you draw perfectly crisp-edged shapes that you can enlarge without
losing quality because they’re made of vectors (see page 52), just like Photoshop text.
See Chapter 13 to learn about the drawing tools and Chapter 14 for more on working with text.
• The Pen tool (P), whose icon looks like an old-fashioned fountain pen nib (see
Figure D-8, left), lets you draw a line by clicking in one spot and then clicking
elsewhere to add anchor points, in between which Photoshop places a line called
a path. You can use it to create amazing illustrations and complex selections. It’s
discussed at great length in Chapter 13 starting on page 541.
Figure D-8: Left: You can use Photoshop’s Pen tool to draw
lines and shapes (called paths—see page 541).
Once you’ve drawn a path, you can place text
on top of it to send your words in any direction
you want.
Right: Use these tools to add text to your documents. Photoshop can do some amazing things
with text, as explained in Chapter 14.
• The Freeform Pen tool (P) lets you draw with the Pen tool freehand. It limits
you to starting and ending anchor points, but it gives you the freedom to draw
any line shape without stopping to add extra points along the way. (You can
always go back later and add more points if you need to refine your shape.) The
box on page 552 has more info.
• The Add Anchor Point, Delete Anchor Point, and Convert Point tools let
you edit shapes you’ve drawn with the Pen tool. They’re discussed in Chapter
13 (page 557).
• The Horizontal and Vertical Type tools (T) let you add text to your image. As
you might suspect, the Horizontal Type tool creates text that runs left to right
and the Vertical Type tool creates text that runs top to bottom. You use the Options bar to choose a typeface, point size, and so on. Chapter 14 teaches you all
about these tools, as well as a fair amount about typography.
• The Horizontal and Vertical Type Mask tools (T) let you create the outline of
text that you can fill, stroke (outline), and use like any other selection. They’re
great for applying special effects in the shape of text. See page 589 for some cool
ideas on how to use these unique tools.
• The Path Selection tool (A) lets you choose paths you’ve created with the Pen
tool, shapes you’ve converted to paths, and even text (see page 595). Its icon
looks like a black arrow (see Figure D-9, left) and it’s described beginning on
page 558.

3-D and View Tools
Figure D-9: Left: After you draw a path (page 541), you can edit
it with the Path Selection and Direct Selection tools.
Right: Objects you draw with Photoshop’s Shape
tool are editable, which means you can resize
them, change their color, and apply effects to them.
They’re also vectors (page 52) so you can make
them bigger without ending up with jagged edges.
• The Direct Selection tool (A) lets you grab anchor points or parts of paths instead of whole paths. Its icon looks like a white arrow with a black outline. Just
like the Path Selection tool, it’s covered in Chapter 13 (page 558).
• The Shape tools (U) let you draw all kinds of shapes that are made out of vectors (page 52). Sure, you can draw rectangles and ellipses with the Marquee
tools (page 139), but they aren’t nearly as versatile because shapes are made
from points and paths instead of pixels. Each Shape tool’s icon looks like the
shape it creates: Rectangle, Rounded Rectangle, Ellipse, Polygon, Line, and Custom Shape (which looks like a funky star). You can see these tools in action in
Chapter 4, page 146, and on page 551 in Chapter 13.
3-D and View Tools
Photoshop CS5 Extended includes a set of tools for working with three-dimensional
objects. They let you edit 3-D objects made with programs like Adobe Acrobat 3D Version 8, 3D Studio Max, Alias, Maya, and Google Earth (which create .u3d, .3ds, .obj,
.kmz, and .dae files, respectively). You can also build your own 3-D shapes and rotate,
animate, and add lighting effects to them. For more on Photoshop CS5’s 3-D capabilities,
download the info posted on this book’s Missing CD page at www.missingmanuals.com/
cds (it’s listed under Chapter 3).
The standard version of Photoshop CS5 doesn’t include these 3-D tools, but it does
include the Hand, Rotate View, and Zoom tools, which are also covered in this section.
Note: In Photoshop CS4, the Hand, Rotate View, and Zoom tools lived in the Application bar as well as
the Tools panel, but in CS5 they were relegated back to the bottom of the Tools panel from whence they
came, freeing up more space for Live Workspaces (see page 18).
• The 3D Object Rotate tool (K) lets you click and drag 3-D objects to spin them
end over end or from side to side (see Figure D-10, left). Dragging up or down
spins the object end over end on its x-axis, and dragging them left or right spins
it from side to side on its y-axis.

3-D and View Tools
Figure D-10: Left: These tools let you change your view of 3-D
objects by moving them around in space.
Right: These tools let you change your perspective
on 3-D objects while leaving the items in place.
• The 3D Object Roll tool (K) lets you spin a 3-D object around its center point
(its z-axis—see the box on the next page). Just drag your object to send it on its
circular journey.
• The 3D Object Pan tool (K) moves 3-D objects up and down or side to side so
you can get a better view of them.
• The 3D Object Slide tool (K) lets you move 3-D objects closer to you or farther
away from you. Drag up and down to change an object’s distance from you, or
drag from side to side to move it left or right.
• The 3D Object Scale tool (K) resizes your 3-D object. Drag up to make it bigger
or down to make it smaller.
• The 3D Rotate Cameral tool (N) rotates your virtual camera on its x-axis.
• The 3D Roll Camera tool (N) rolls your virtual camera on its z-axis, which
makes it look like you’re spinning while the object remains stationary.
• The 3D Pan Camera tool (N) creates a panning effect so you can view different
parts of a stationary object by moving along the x- and y-axes.
• The 3D Walk Camera tool (N) lets you move around an object as if you were
walking around it. You can move forward and back along the y- and z-axes.
• The 3D Zoom Camera tool (N) lets you drag to narrow the camera’s field of
view and focus in on the object’s details. You can also zoom out for a big-picture
view.
• The Hand tool (H) is much more than a disembodied Mickey Mouse glove (see
Figure D-11). It serves as a digital version of your own hand and lets you move
images around on your screen. (It’s especially helpful when you’re zoomed in.)
When you drag an image with the Hand tool, you’re not actually moving the image in your document, you’re just changing which part of the image you see. You
can also use it to “toss” your images around if you have flick-panning turned on
(see page 64). In addition to its keyboard shortcut, you can summon this tool
anytime by pressing your space bar.

UP TO SPEED
Understanding Photoshop’s Axes
Since the images you work with in Photoshop are really two
dimensional—even if you’re working with 3-D objects—Photoshop uses the terms x-axis, y-axis and z-axis to describe
simulated 3-D movements in your document’s 2-D world.
The x-axis represents horizontal (left and right) movement,
the y-axis represents vertical (up and down) movement,
and the z-axis represents changes in depth (forward and
backward movement).
If this axis thing sounds familiar, it’s no surprise. These are
the same principles you used to make graphs in math and
science classes. If you ever wondered how those graphing
skills would come in handy later in life, now you know.
Figure D-11: The lower portion of the Tools panel includes the Hand, Rotate View, and Zoom tools,
along with the foreground and background color chips and Quick Mask Mode button.
• The Rotate View tool (R) lets you rotate your view of an image to give you a
more natural angle for painting or drawing—without rotating the image itself
in the document. Its icon looks like a hand in front of a diamond shape; you can
find it in the Hand toolset. Page 65 has the scoop on using this tool.
• The Zoom tool (Z), whose icon looks like a magnifying glass, lets you zoom in
to take a closer look at what you’re editing. When you grab this tool and then
click your image, you can keep zooming until you reach 3,200 percent magnification; Option-click (Alt+click on a PC) to zoom out. See page 60 for more info.
Foreground and Background Color Chips
As explained on page 24 in Chapter 1, you can only work with two colors at a time:
a foreground color and a background color. You can tell which colors those are by
looking at the bottom of the Tools panel (see Figure D-11), where you see two overlapping colored squares (the foreground color is the one on top). Flip back to page
24 to learn how to change these colors and what you’ll use ’em for.
Quick Mask Mode
At the very bottom of the Tools panel is the Quick Mask Mode button, which looks
like a circle within a rectangle. When you click this button (or press Q), Photoshop
plops you into Quick Mask mode, where you can paint to create or edit a selection.
It’s described in detail on page 176.
